Yield<br />
• Bolts in bearing joints are designed to meet two limit states:<br />
1. Yielding, which is an inelastic deformation (above left)<br />
2. Fracture, which is a failure of the joint (above left)<br />
• The material ilthe bolt bears against is also subject to yielding ildi or fracture if it is<br />
undersized for the load (above right)<br />
• Tension connections act similarly to bearing connections<br />
29<br />
• Many times, connections in direct tension are reconfigured so that the bolts act<br />
in shear<br />
